Maryland CAR DMV Practice Test 21

Even if your light is green, you must not enter an intersection unless you can get completely through the intersection before the light turns red. If you block the intersection, you can be cited.

When a steady yellow light appears on a traffic signal, you should prepare to stop. If you are already within the intersection, you should clear the intersection as quickly as possible.

When a school bus is flashing its red lights and has its stop arm extended, motorists must come to a full stop until the lights are turned off, the stop arm is withdrawn, and the bus begins moving again.

This sign indicates that there is a crossroad ahead.

Watch for any pedestrian who may cross your path. If you see pedestrians near the road where you are driving, slow down and be prepared to stop, if necessary.

Only use your horn when it is necessary to avoid collisions. Do not use your horn if a driver or bicyclist is moving slowly and you want him or her to drive faster or get out of your way.

Collisions are more likely to happen when one driver moves faster or slower than the other vehicles on the road. Driving faster than other traffic increases your chance of being involved in a collision. Driving more slowly than other traffic is also dangerous because it can increase the risk of a rear-end collision with your vehicle or cause other drivers to swerve to avoid hitting you.

A five-sided yellow or yellow-green sign alerts drivers to either a school zone or school crossing.

This sign alerts you to the possibility of traffic merging into the main stream of travel. After checking to your side and rear, you should move into another lane, if possible, to allow merging motorists a clear path.

Warning signs are usually yellow with black markings. This sign indicates that there could be traffic merging from the right, so drivers should prepare to allow traffic to safely merge.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

Maryland Vehicle Law prohibits any use of handheld cell phones while operating a motor vehicle. Although hands-free devices are permitted, drivers should minimize calls and focus on safe driving practices. Any use of a cell phone while driving is considered distracted driving and increases the risk of an accident.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

Warning signs are usually yellow with black markings. This sign indicates that a divided highway is beginning and cars should keep to the right.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that you are leaving a separated one-way highway and will soon be driving on a two-way highway.

This sign indicates that the road ahead may be slippery when wet.

Orange warning signs are used in and around work zones. Use special caution when you see orange signs, cones, or barriers on a roadway.

You should always signal when turning, changing lanes, slowing down, or stopping so that other drivers, motorcyclists, bicyclists, and pedestrians will know your intentions.

While driving, you should remain aware of the actions of surrounding drivers. If you notice an aggressive driver nearby making erratic or improper lane changes, you should not challenge them. The safest way to handle an aggressive driver is to get out of their way.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

To avoid contributing to chronic traffic congestion, you should not "rubberneck." That is, you should not slow down to look at out-of-the-ordinary things.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers of an upcoming intersection so they may prepare for potential traffic or prepare to turn.

It is not advisable to drive after drinking any amount of alcohol. Even a single drink will affect your ability to drive safely.

The flashing overhead lights and stop arm on a school bus will be activated when the bus is stopped to load or unload students. If approaching a bus using these signals, you may not proceed until the red lights have stopped flashing and the stop arm has been retracted. Never pass a school bus that is dropping off or picking up students.

If you begin to skid on a wet or icy road, take your foot off the accelerator, stay off the brakes, and turn your steering wheel in the direction of the skid. However, if you have anti-lock brakes, you should apply your brakes firmly and steer straight ahead.
